The interview schedule used for this survey was jointly developed by Westinghouse and Korea Institute of Family Planning. Westinghouse developed a model questionnaire designed to collect contraceptive prevalence and other information important to family planning program management as part of a large international survey effort. The questionnaire was modified to reflect the unique situation and specific data needs of Korea. The questionnaire had two major parts, the individual questionnaire and the household questionnaire. The individual questionnaire was administered to an eligible respondent in each sample household. It covered five major subject matter areas: demographic and background characteristics, fertility experience, contraceptive awareness, contraceptive experience and availability of contraceptive supplies and services. The household questionnaire which was administered to all sampled households regardless of the presence of an eligible respondent, collected data on household characteristics and major demographic events experienced by the household. The household schedule collected information on: births (occurring to household members in the last year), deaths (occurring to household members in the last year), induced abortion (occurring to household members in the last year), household size and composition, and material and child health.
